When this entrepreneur started selling books on Amazon in August 2024, he had no savings, no office, and no home. He was sleeping in his car. Fifteen months later, he had generated over $150,000 in revenue from 148 self-published books.
His platform of choice was Amazon KDP (Kindle Direct Publishing), a print-on-demand service that prints and ships physical books only when a customer places an order. No inventory, no upfront manufacturing costs. Just the book, the listing, and the algorithm.
Starting With Volume, Not Vision
His first move was not to chase a passion project. It was to gather data. He published dozens of low and medium-content books including logbooks, prompted journals, and coloring books to identify which niches had real demand and weak competition. Most of those early titles sold fewer than ten copies. That was fine. They were experiments, not products.
Once patterns emerged, he moved into higher-quality books in proven niches, eventually hiring two full-time writers, a layout designer, and an illustrator. Around 70 percent of his catalog is now produced by his team.
The Numbers Behind the Business
His results over 15 months break down like this:
- Total revenue: $150,000
- Ad spend: $16,000
- Employee costs: $24,000
- Tools and subscriptions: $2,500
- Profit before tax: approximately $100,000
Last month alone, he brought in $32,000 in revenue.
What Actually Moves the Needle
He ran Amazon ads not primarily for direct sales, but for data. The platform reveals almost nothing about customer behavior, and ads gave him a window into impressions, clicks, and conversions.
He also learned that relevance matters more than reach. When he added trending but unrelated keywords to two of his books, monthly sales fell from around 20 to single digits, and removing those keywords did not fix the damage.
Cover design, he says, is second only to niche selection in importance. A cover is not art. It is a pitch. If it does not match or beat the quality of top competitors, the book will not sell.
He also built email lists in his best-performing niches. When he launched a new book to a list of 1,000 subscribers with a release-day discount, he recorded over 200 sales on day one, enough velocity to climb the rankings and keep climbing.
A Business, Not a Lottery Ticket
Serious_Desire does it well tracking margins, payback time, and unit economics on every title. He writes standard operating procedures for contractors. He plans for seasonality. He sets aside money for taxes.
For anyone thinking about starting, his advice is simple. Publish something. Learn from it. Then publish something better.
